embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
With reference to Fig. 1, the high-voltage ring main unit of a kind of electromagnetic lock concealed installation embodiment illustrated in fig. 2, comprise cabinet 1, lower cabinet body 2, described upper cabinet 1 is provided with Over-The-Counter door 11, described lower cabinet body 2 is provided with lower cabinet door 21, the top side of lower cabinet door 21 is provided with jam plate 22, in described upper cabinet 1, be provided with electromagnetic lock 14, described electromagnetic lock 14 is fixed on the upside of the interior base plate 17 near cabinet door of cabinet 11, described upper cabinet 1 base plate 17 has a locking bolt hole 18, the locking bolt 143 of described electromagnetic lock 14 can be arranged in described locking bolt hole 18, described jam plate 22 is provided with jack 23, the locking bolt 143 of described electromagnetic lock 14 can be arranged in described jack 23 by locking bolt hole 18.
Because electromagnetic lock 14 is fixed on the upside of the interior base plate 17 near cabinet door of upper cabinet 1, when Over-The-Counter door 11 is closed, described whole electromagnetic lock 14 is covered by Over-The-Counter door 11.
With reference to Fig. 3, when a kind of high-voltage ring main unit of electromagnetic lock concealed installation is incoming line cabinet, whether electrification in high voltage transducer to respond to inlet wire cable charged if being housed on the long cable section of ingoing line cabinet threephase cable sleeve pipe of described lower cabinet body 2, electrification in high voltage sensor sensing electric charge loop series connection high-voltage charge display device 15, whether high-voltage charge display device 15 can indicate inlet wire cable charged, the upper external direct current of binding post XB1/1-1 or alternating current 220V, high-voltage charge display device 15 output break-make axle auxiliary contacts (DXN:3-4) are normally closed contact, the normally closed contact of circuit breaker or on-load switch (QF:5-6) is connected in the actuating coil loop of electromagnetic lock 14.
When inlet wire cable is charged, high-voltage charge display device 15 output break-make axle auxiliary contacts (DXN:3-4) disconnect, now not conducting of electromagnetic circuit, and electromagnetic lock 14 is blocking, when high-voltage charge display device 15 operation irregularities, and in circuit breaker or on-load switch combined floodgate situation, when high-voltage charge display device 15 output break-make axle auxiliary contacts (DXN:3-4) normally do not disconnect in the situation that inlet wire cable is charged, now the normally closed contact of circuit breaker (QF:5-6) is off-state, the loop of electromagnetic lock 14 still cannot conducting, electromagnetic lock 14 is blocking, avoid in circuit breaker or on-load switch combined floodgate situation, when high-voltage charge display device 15 output break-make axle auxiliary contacts (DXN:3-4) have normal disconnection in the situation that inlet wire cable is charged, electromagnetic lock 14 does not have the problem of correct locking.
When inlet wire cable dead electricity, high-voltage charge display device 15 output break-make axle auxiliary contact (DXN:3-4) closures, circuit breaker again when gate-dividing state the normally closed contact of circuit breaker (QF:5-6) be closure state, electromagnetic lock 14 loop conductings, electromagnetic lock 14 is released state.
Referring to Fig. 4, on the basis of a upper embodiment, when the high-voltage ring main unit of described a kind of electromagnetic lock concealed installation is outgoing line cabinet, the normal opened contact (QF:5-6) that the normally closed contact of circuit breaker or on-load switch (QF:5-6) is replaced by ground cutter is connected in the actuating coil loop of electromagnetic lock 14.
When inlet wire cable is charged, high-voltage charge display device 15 output break-make axle auxiliary contacts (DXN:3-4) disconnect, now not conducting of electromagnetic circuit, electromagnetic lock 14 is blocking, when high-voltage charge display device 15 operation irregularities, and in ground cutter separating brake situation, when high-voltage charge display device 15 output break-make axle auxiliary contacts (DXN:3-4) normally do not disconnect in the situation that inlet wire cable is charged, now, the normal opened contact (QF:5-6) of ground cutter is off-state, electromagnetic lock 14 loops still cannot conducting, and electromagnetic lock 14 is blocking.
When inlet wire cable dead electricity, high-voltage charge display device 15 output break-make axle auxiliary contact (DXN:3-4) closures, the normal opened contact (QF:5-6) of ground cutter circuit breaker when "on" position is closure state, electromagnetic lock 14 loop conductings, and electromagnetic lock 14 is released state.
When lower cabinet body 2 cable vault's inner cables are when charged, electromagnetic lock 14 lockings, the locking bolt 143 of described electromagnetic lock 14 stretches out locking bolt hole 18 downwards and is arranged in described jack 23, realizes the electric blocking of 14 pairs of lower cabinet doors 21 of electromagnetic lock.
When electromagnetic lock 14 breaks down, can directly to electromagnetic lock 14, dismantle, and need not have a power failure, open lower cabinet door 21 and again electromagnetic lock 14 is removed to maintenance.
Locking bolt hole 18 is perpendicular to the jack 23 of described jam plate 22,18Wei two ends, locking bolt hole have the rectangular opening of circular arc, the shape of the locking bolt 143 of described circular arc and described electromagnetic lock 14 matches, can make when electromagnetic lock 14 locking, the locking bolt 143 of electromagnetic lock 14 is better stretched in locking bolt hole 18.
As further improvement of this embodiment, a side of the unlock button 142 of electromagnetic lock 14 faces Over-The-Counter door 21, and person easy to use carries out the operations such as use and maintenance maintenance to electromagnetic lock 14.
As preferably, during electromagnetic lock 14 locking, the locking bolt 143 of described electromagnetic lock 14 is the more than 1/3rd of locking bolt 143 of electromagnetic lock 14 through the length of jack 23, can make better keep lower cabinet door 21 is fixed of electromagnetic lock 14.As preferably, described Over-The-Counter door is provided with transparent toughened glass transparent panel, described toughened glass transparent panel 16 is in the bottom side of Over-The-Counter door 11 and relative with the position of electromagnetic lock 14, can, can observe directly by described toughened glass transparent panel 16 blocking 142 of electromagnetic lock, the electrification display state 141 of electromagnetic lock when cabinet door 11 is closed, and need not open Over-The-Counter door 11, check.
